This keto peanut butter chocolate cake is a delicious and healthy dessert that's perfect for anyone following a keto diet. The cake is made with almond flour and coconut flour, which are both low in carbs and high in fiber. The peanut butter provides a good source of protein and healthy fats, while the dark chocolate is rich in antioxidants. To make the cake even more keto-friendly, you can use a sugar substitute like stevia or erythritol instead of regular sugar. Serve it with a dollop of whipped cream or a sprinkle of cocoa powder for a dessert that's both keto and delicious.
